One of the key things you’ll calculate in Excel are values in cells, the boxes you see in the grid of an Excel worksheet. Each cell is identified by its reference—the column letter and row number that intersect at the cell's location. For example, a cell in column D and row 5 is cell D5. When you use cell references in a formula, Excel calculates the answer automatically using the numbers in the referenced cells.

Sometimes you need to enter a lot of repetitive information in Excel, such as dates, and it can be really tedious. But the AutoFill feature can help. Or say you have information in Excel that isn’t formatted the way you need it to be, and going through the entire list manually to correct it is daunting. In this case, Flash Fill (a new feature in Excel 2013) can do the work for you. AutoFill and Flash Fill are tremendous time savers, and in this course, we’ll cover them in more detail.

You can add and subtract time in Excel almost like you subtract other types of numbers. For example, you might do this if you want to know how long it took to complete a project’s tasks. The one exception is that Excel doesn't support a negative number formatted as time.

When you need to find an average, you can click a button, or use a function in a formula. The AutoSum button lets you find the average in a column or row of numbers where there are no blank cells. Use the AVERAGE or the AVERAGEIF functions to find the average of numbers that aren’t in a contiguous row or column. And use the SUMPRODUCT and the SUM functions to find a weighted average, which depends on the weight that’s applied to the values.

You can add headers to the top and footers to the bottom of a worksheet. When you print the worksheet, the headers and footers also print. For example, you might create a header with the file path and a footer with page numbers. Headers and footers display only in Page Layout view and on printed pages.

In the course Use conditional formatting, we covered the basics of conditional formatting. Here, we'll go a few steps further and see how to apply conditional formatting to cells, tables, PivotTables, and worksheets. For example, to quickly conditionally format cells, you can use a Quick Analysis option or an option on the Conditional Formatting button in the ribbon. We'll also use formulas to apply conditional formatting, and learn how to edit and delete rules using the Conditional Formatting Rules Manager.

It can be hard to get a lot of meaning out of numbers in a worksheet. But Excel provides a bunch of ways to quickly analyze your data using conditional formatting. For example, you can use a color scale to differentiate high, medium, and low temperature values.

You can make a worksheet more efficient by providing drop-down lists. Someone using your worksheet clicks an arrow, and then clicks an entry in the list. Take this course to learn more about how best to use and manage them.
